Like, I get the idea. There’s a bit of ramp up, there’s a resource to be managed. But even ignoring the fact that it just isn’t a fun mechanic I think I have probably seen more player toxicity result from Warp Charges than any other mechanic in the game.
I’m sure we’ve all seen an argument between a psyker who is beyond salty that people keep popping his BB targets. And that’s fair, when you’ve spent 10-15 seconds faffing about building up to 6 charges because your entire build is centred on making you more powerful and some guy shoots the random poxwalker in the corner of the room you were using to refresh your charges meaning you have to start all over, that’s UNBELIEVABLY IRRITATING. It’s also fair that expecting people to think about every single random mob just in case the psyker needs to kill it is also unbelievably irritating.
Your three choices are micromanage everyone around you (which will make everyone but especially pubs hate you), trust pubs to be conscientious teammates (ha) or simply stop trying and instead not utilise your feats and toolkit.
Either make it last a lot longer or make it last a lot shorter but generated from all warp attacks, but it simply can’t stay as it is. Everyone knows it’s a pain and no one likes playing around it.
